Answer:

x = 28/3

Step-by-step explanation:

We can solve this problem by using similar triangles:

Both of these triangles have a 90 degree angle and they share angle A, meaning that they are similar by AA similarity.

Now we can set up ratios and solve:

13/7 = (x+8)/x

multiply both sides by x:

13x/7 = x+8

Multiply both sides by 7:

13x = 7x + 56

move the 7x over and divide by 6:

6x = 56

x = 28/3

Answer:

9 1/3 or 9.3333333333

Step-by-step explanation:

Triangle ABC is similar to Triangle ADE because they are proportional.  It is a 7:13 ratio as shown by segments CB and ED.

Therefore, the ratio from AB to AD would also have to be 7:13.  The ratio as shown by the picture is x:x+8.  Therefore x:x+8=7:13.

Now you put this in fraction form.  \frac{x}{x+8}=\frac{7}{13} You multiply both sides by X+8 and get X=\frac{7x+56}{13}.  Now you multiply both sides by 13 and get 13X=7x+56.  Now you have cleared the fractions so it looks neater.  Next, you subtract both sides by 7x and get 6x=56.  Finally you divide both sides by 6 and get x=9 1/3

1. Sam knows that his MP3 player has 40% of its battery life left and that the battery
Korolek [52]

Complete question :

Sam knows that his MP3 player has 40% of its battery life left and that the battery

charges by an additional 12 percentage points every 15 minutes. What percent of

the mp3's battery will be charged when Sam and his family leave? If mp3 was plugged in an hour before his family plan to leave.

Answer:

88%

Step-by-step explanation:

Time before leaving = 1hour

Current percentage = 40%

Charge rate = 12% every 15 minutes

Therefore,

Charge rate per minute :

12% / 15 = 0.8% per minute

Charge recieved after one hour (60 minutes) :

0.8% * 60

= 48%

Therefore, total charge after just before leaving is:

Current percentage + percentage received

40% + 48%

= 88%

What is the y-intercept of the liner function? (y=3x-2)
inysia [295]

The y-intercept of the linear function y = 3x - 2 is -2

<h3>How to determine the y-intercept?</h3>

The function is given as

y = 3x - 2

The above function is a linear function, and the y-intercept is the point on the graph, where x = 0 i.e. the point (0, y)

As a general rule, linear functions are those functions that have constant rates or slopes

Next, we set x to 0, and calculate y to determine the value of the y-intercept

y = 3(0) - 2

Remove the bracket in the above equation

y = 3 * 0 - 2

Evaluate the product of 3 and 0 i.e. multiply 3 and 0

y = 0 - 2

Evaluate the difference of 0 and -2 i.e. subtract 0 from 2

y = -2

The above means that the value of y when x is 0 is -2

Hence, the y-intercept of the linear function y = 3x - 2 is -2

which best explains whether a triangle with side lengths 2 in., 5 in., and 4 in. is an acute triangle?
sdas [7]

Answer:

Obtuse triangle.

Step-by-step explanation:

Side a = 5

Side b = 2

Side c = 4

Angle ∠A = 108.21° = 108°12'36" = 1.88862 rad

Angle ∠B = 22.332° = 22°19'54" = 0.38976 rad

Angle ∠C = 49.458° = 49°27'30" = 0.86321 rad

Since one angle is above 90 degrees, the triangle is obtuse triangle.

This cannot be an acute triangle.
